What are the key features of LM317LIPWG4?
- Adjustable 1.2 V to 32 V output voltage set by two external resistors, covering a wide range of low-current regulated supply requirements in a single device
- 0.05%/V line regulation minimizes output variation across input supply changes, ideal for precision low-current reference and bias circuits
- 8-pin TSSOP package enables compact PCB placement versus through-hole TO-92 equivalents, reducing board footprint by over 75% in space-constrained designs
What is LM317LIPWG4 used for?
The LM317LIPWG4 is ideal for low-current adjustable bias supplies in analog signal-conditioning circuits, op amp dual-supply references, and precision ADC reference generators where an output between 1.2 V and 32 V must be set with two resistors. It also suits LED current-setting circuits and small motor driver pre-regulators in industrial and consumer electronics that draw no more than 100 mA continuously. The compact TSSOP footprint makes it a convenient drop-in solution for portable instruments and bench power supplies that require a clean, adjustable low-noise rail.

Frequently Asked Questions
Over what output voltage range can the LM317LIPWG4 be configured, and how is that range set?
The LM317LIPWG4 is adjustable from 1.2 V to 32 V by changing the ratio of two external resistors connected to the ADJ pin. The 1.25 V reference voltage and the resistor divider allow engineers to hit any voltage in this 1.2 V to 32 V span with standard E24-series resistor values.
What is the maximum output current of the LM317LIPWG4, and for which load types is it appropriate?
The LM317LIPWG4 is rated for a maximum continuous output current of 100 mA, making it suitable for analog bias supplies, op amp offset trimming networks, LED bias circuits, and low-power microcontroller reference rails that draw less than 100 mA.
How does the LM317LIPWG4 compare with its TO-92 predecessor for SMT PCB assembly?
Switching from the through-hole TO-92 package to the 8-pin TSSOP in the LM317LIPWG4 reduces the component height to under 1.2 mm and the PCB footprint by more than 75%, enabling automated SMT pick-and-place assembly and eliminating the manual insertion step required for through-hole parts in mixed-assembly production lines.
What line-regulation performance does the LM317LIPWG4 offer, and why does it matter for sensor excitation supplies?
The LM317LIPWG4 achieves a maximum line regulation of 0.05%/V, meaning a 1 V change in input voltage shifts the output by no more than 0.5 mV at a 10 V output. In a Wheatstone-bridge excitation circuit, this keeps bridge offset below 10 µV/V sensitivity—meeting the requirements of most strain-gauge and pressure-sensor applications without additional post-regulation.
